UAS regulatory sequences drive expression of a full-length ato open reading frame.
atoUAS.cYb/Scer\GAL4ato.5'EYE3' rescues ato1/Df(3R)p13
Expression of atoScer\UAS.cYb under the control of Scer\GAL4ato.eye rescues the loss of eye phenotype found in ato1/Df(3R)p13 flies. However, ordered ommatidial packing is not restored as a number of supernumerary R8 cells are still present.
